To all whom t may concern,.-

Be it known that I, MosEs A.' KELLER, a citizen of the United States, residing at Batavia, in the county of Genesee and State of New York, have invented anew and 'useful Improvement in a Combined Compressor and Trip Mechanism for Self-Bindin g Harvesters,

operates in conjunction with a stationary switch, whereby the compressor is sustained in its upright position until the needle begins to recede, when said switch will cause the compressor to drop below the binding table to allow the bound gavel to pass out of the binder and as the needle reaches its normal position, the compressor is lifted toits nor- `mal position, by reason of its being coupled to the needle and wholly supported by the needle shaft, and the needle; second,by forming or having the clutch arm rigidly secured on the needle shaft, and the cranked arm journaled on the said shaft, and made to catch under said' trip arm, and the operating pitman connected to said arm, and the main gear on the knotter operating shaft, and a tension spring connecting the trip arm, and cranked arm together whereby when thecompressor rocks the needle shaft will unclutch g the trip arm against -the resistance of the said spring and setin motion the binding mechanism. By this construction and arrangement, I dispense with the special trip shaft, the compressor shaft and spring compressor link, and the cam mechanism in the main gear on the knetter operating shaft. In all it will save from one dollar to two dollarsin first cost over the 'regular trip mechanism in general use, and by its simplicity and few working joints will be less liable to get outof order and insure better work of the machine. I attain these objects by the mechanism illustrated in the accompanying drawings, inwhichi Figure l is a right hand side elevation or gear side of the-binding mechanism. Fig. 2 is a rear side elevation also in the normal position. Fig. 3 is a left hand side elevation also in the normal position. Fig. 4 is a left hand side elevation of the compressor mechanism and needle as the same are in operation compressing a gavel. Fig. 5 is another left hand side view of lthe compressor mechanism as the same would appear when fully compressed home in the operation of binding a gavel. Fig. 6 is another left hand side View showing the position of the compressor and needle, while the bound gavel is being discharged from the binding table. Fig. 7 shows detail parts of the switch plate and Fig. 8 shows detail parts of theclutch mechanism. Fig. 9 is atop view of the operating gears, the compressor mechanism and frame, the latter partially in section. Fig. IO is aright hand side view of the clutch mechanismand compressor with switch plate removed but shown in dotted lines. Fig. l1 is a left hand side view, of the compressing mechanism with the compressing link removed to show how the compressor is supported in its upright and normal position. Fig. 12 is a plan view of the needle shaft with its clutch operating arm and the operating crank arm, and Figs. 13, 14, l5, I6 and 17 are detail parts of the compressor mechanism.

Similar letters and figures of reference refer to similar parts throughout the drawings, in whichl A denotes the main frame of the binding mechanism, and A the supplemental frame to which the operating gears are secured and which also supports the table B.

Journaled in the upper arm of the frame A is the main knotter'operating shaft., to which is secured the main knetter operating wheel B, the knotter operating segment wheel O and the gavel ejector arms T. Into the lower arm of the frame A is journaled the needle oper ating shaft F.

To the supplemental frame A is journaled the packer cranked shaft U and the clutch shaft Y. The gear wheels V and H2 are rigidly secured on their respective shafts, and the clutch driving disk E2 is also rigidly affixed to the shaft Y. The clutch holding disk E2, and the sprocket wheel B4 are in one piece and are journaled on the shaft between the gear H2, and clutch driver E2. An endlesschain O connects the wheel B with the wheel B4, the

latter being theldriver. On the end ofthe needle shaft F, is formed or secured the clutch trip arm G, which has a hook at its free end to engage the clutch dog 11 when in its normal position as shownl in Figs. 1 and 2.

Journaled on the needle shaft between the frame A and the clutch trip is the needle operating pitman arm E. A bolt with a spring D2 holds the clutch trip arm and the needle operating arm together in the manner as shown in Fig. 1, and by reference to the drawings Fig. 12 it will be seen that the arm E catches under the trip arm G and they are held together by the action o1'A power of the spring D2 as shown in Figs. 1 and 9. The arm Eis connected-by a pitman D to a crank pin 12, that is on the wheel B. See Figs. 1 and 2.

The needle H. is rigidly secured on the shaft F and has a short crank arm L2. See Fig,.11. Into this crank is secured a pin or stud R. The compressor I is provided with two long slots P. and Q. as shown in Fig. l1 and by these holes is supported on the needle shaft F and stud R, while inthe normal position as shown in Figs. 1, 2, 3 and 11.

Formed at the heel of the compressor is a projecting arm 16, on which is a compression spring R, a coupling link J and provided with a hole to receive the arm 16, and by a hole 20 is journaled on the stud R. in the manner as shown in Fig. 9, and several others, and the spring K is thus between the end of the coupling link and heel ofthe compressor, as clearly shown in Figs. 9 and 10. The end of said link is bent at right angles tothe body of the link, as shown in Figs. 9 and 18, and on this end is journaled a roller L.

There is a switch plate M secured to the lower arm of the frame A. as shown in Figs. 1, 2, 3, 4, 5, 6 and 9. On the face ofthis plate is journaled a small angular switch N on a pin or stud 9,1and is also provided witha pin 10, which enters the slot 3 in the plate, and projects through said slot and is engaged by a spring Z, see Figs. 7 and 9, and by this spring is held yieldingly in its normal position. There is also formed on the face ofthe plate M a projection or foot S and a projecting ange 2.

On Fig. 8 is given a plan of the construction of the clutch mechanism. As will be seen the clutch dog l1 is jonrnaled to the face of the disk G2 and a spring F2 holds the roller 13 of the dog 11 in Contact with the catches 14, that are formed on the inside of the fiange of the driving disk E2, as seen in dotted lines, but when the clutch dog is arrested and held by the trip arm G. the dog 11 will be in the position shown in Fig. 1 and the bindingmechanisrn will then be out of gear and the dog 1l out of contact with the driving disk E2.

Having thus given the general construction of the improved mechanism its operation as a whole is as follows: The grain as it accumulates on the table B is caught by the usual packer XV and packed between the table and breast plat-e of the knotter against the compres'sor I., until the pressure of the grain against the compressor will cause the compressor to yield. Provision for this yielding is made in the switch plate M. When the compresser is in its normal position the roller L. with respect to the switch N. is in the position as shown in Fig. 3 and is held in this position by the force of the spring D2 that is on the trip arm G; but when the compressor has yielded under the pressure of the grain to the position shown in dotted lines 7 Fig. 3 it has vibrated the needle to the point indicated by the dotted lines S, Fig. 3, and consequently has vibrated the needle shaft F and trip arm G against the resistance of the spring D2, for the reason that the arm E was held rigid by the pitman D, but this action of the yielding of the compressor has lifted the trip lever out of contact with the clutch dog 1l as shown in Fig. 10, and the roller L. of the compressor now rests on the vibrating switch N. as seen in Fig. 10 or in dotted lines Fig. 3. The lifting of the trip lever G. from the dog 11 has now set in operation the main wheel B through the chain C in the manner before described; and the pitman now lifts the arm E and draws it against the trip arm G to the full stroke of the crank pin l12, and as seen in dotted lines 15 Fig. 1; and by this operation the needle H is also brought up which divided the grain and compressed it against the compressor and this pressure holds the roller L down on the switch N which will cause the switch to assume theposition as shown in Fig. 4, and thereby close the open space 21, to allow the roller to pass over unto the foot S. without allowing the compressor to lower, and when the needle has been carried home to the knotter the pin R which actuates the compressor has now placed the compressor, the link J and roller L in .the position shown in Fig. 5 and` the spring Z has returned the switch N. to its normal position, as shown in Figs. 5, and 7, and thus opened the space 21. Now as the needle H begins to recede the pin R will push back the link J until the roller L passes oit the foot S and drop through the opened space 2l, and thus allow the compressor I to fall below the table B F, as seen in Fig. 6 and thus allow the ejector arm T to remove the bound gavel 5; and as the needle continues to recede, the pin R will again assume the position in the slot Q as shown in Fig. 11 and lift the compressor to its normal position. During this operation the roller L will again come in collision with the switch N in the manner shown in Fig. 15, and when the roller has reached its normal position shown .in dotted lines 22, same ligure, the spring Z will again restore the switch to its normal position and prevent the compressor to drop too far under pressure of the grain. XVhile the flange 2 prevents the compressor to fly up out of its proper position, simultaneously with this movement of the compressor and needle, the trip arm G will catch the clutch dog 1l and draw it out of engagement with the disk E, and thereby IOO IIO

I stop the sprocket wheel B4 and consequently provided with a slotaround said shaft, and

having a similar slot about a stud or pin that is secured in the heel extension of the needle or its equivalent, whereby the compressor is wholly supported upon the needle shaft while in its normal position, a switch secured to the lower arm of the binder fraine next the binding needle, a supplemental compressor link journaled on the same pin of the heel extension of the needle, as the compressor, said link having a suitable hole to receive a short arm that is formed on the compressor and a supplemental compressor spring interposed between the rear end of said compressor link and heel of the needle, a projection or roller on said link to operate in conjunction with the switch, to sustain the compressor during the binding operation and at the conclusion of the binding operation cause the compressor to drop below the binding table to allow the bound gavel to pass out, and as the needle continues to recede allow the compressor to return to its normal position, as the needle comes to rest. 2. In acombined compressor andtrip mechanism, the combination substantially as hereinbefore described, of the compressor, a binding needle and its shaft, atrip arm secured or formed on one end of said shaft and the needle at the other end said trip arm adapted to operate in conjunction with the clutch mechanism of the binder, a cranked arm journaled on the needle shaft next the trip arm, and connected by apitman with the main binder operating wheel that is on the main knotter operating shaft, a tension spring connecting the trip arm and cranked arm, to cause the former to engage the clutch dog, the compressorjournaled on the needle shaft next the needle by slots a pin or stud on the heel extension of the needle against which the compressor rests, when in its normal position, a
